请教高手 关于Smarty的问题!!!
如下购物车数组
$carts=array(
1=>array(name=>“Nokia 5510” , price=>800, qty=>2 ),
3=>array(name=>“Nokia 6610” , price=>1800, qty=>1 ),
4=>array(name=>“Nokia 7710” , price=>2800, qty=>1 ),
7=>array(name=>“Nokia 8810” , price=>2500, qty=>5 ),
}
用smarty循环,以表格形式显示购物车,表格行背景色有轮换效果,表格下有总额统计


------解决方案--------------------
在php页面里做好加法,传入smarty模板里就是了。smarty好像不管运算的。

循环加出
$sum
$smarty->assign("sum",$sum);

总金额:{$sum}
------解决方案--------------------
我查了一下手册,可以计算

在Math [数学运算] {assign var="foo" value="`$foo+$bar`"}

你的模板可以写成这样
HTML code
